Technyl polyamide from Rhodia Engineering Plastics, a member of the Solvay group, has been chosen by Röchling Automotive for the manufacturing of turbocharger air ducts which have to resist temperatures of up to 210°C.

Since 2007, teams from Rhodia Engineering Plastics and Röchling Automotive have been working together to develop new solutions to meet the increasingly demanding specifications of automobile OEMs. Fabrizio Chini, Advanced Project Manager at Röchling Automotive explains: “With a full understanding of our needs and a close and efficient collaboration, Rhodia was able to develop a high performance material that meets all the stringent technical requirements for air duct system parts, which also allows us to apply our patented and exclusive JectBonding processing and joining technology.”

As a result, the new polyamide 6.6 blow-moulding material - Technyl B2 - is the established grade in Rhodia’s Technyl range of products for turbo systems and has been used by Röchling Automotive for over a year. “Thanks to Röchling Automotive, our polyamide is already utilized in more than 300,000 automobiles, which fully confirms customer benefits and positions Rhodia’s Technyl range as a benchmark for turbo air duct systems,” says Nicolas Batailley, Business Development Manager, Rhodia Engineering Plastics.

For several years now the automobile industry faces the growing need for smaller yet high performing turbo-charged engines. To meet the increasing material challenges this imposes, Rhodia Engineering Plastics is developing next generation Technyl blowmoulding grades to meet even higher under-the-hood operating temperatures.
